For those who in interest to see how well performed the latest DOSBox with PPC jit on x5000, I made a short video. As usual full-HD, 1920x0180.

To make all captures correctly by the external capturing device I had to set for DOSBox's fullscreen mode 1920x1080 too, so the original game's mode by default looks like some area in the center of the screen, so I had to use big DOSBox's scalers, which is eating CPU as well. But at least it still more or less ok. Locally one may not need such a big resolution, and just most of the time 640x480 fullscreen will be fine (as well as the speed, of course, will be even faster than on video too).

Also together with JIT there SDL2 now instead of SDL1, and I add "normal4x" scaler which not in DOSBox's code by default, but still good to have (especially when you run things on 1920x1080).

So, there is:

Games showed:

Command & Conqueror
Mortal Kombat 3
Cyberia
Little Big Adventure
Chronomaster
Crusader: no remorse


All games showed there are "full CD" ones (except Crusader: no remorse), so in my run scripts I automount ISOs in DOSBox, and music and video and stuff have taken from the CD.

Thanks for watching :)

good job kas1e. i suggest in future to add the 3dfx module too. probably now with jit cpu you will have decent performance with it too.

New video, "DosBOX 0.74 with PPC JIT on AmigaOS4 part 2":

https://youtu.be/1HBic4R-Xsw

This time show a bit more heaver games than before, half of them are 16/24 bit ones, so after endian fixes for this depth more games can be played.

Games showed:

TombRaider (00:10 - 01:50)
Earth2140 (02:00 - 04:30)
MDK (04:40 - 07:00)
The 11th Hour (07:10 - 11:05)
Fallout (11:15 - 14:00)
Rayman (15:25 - 17:20)

At last, after ~15 years, I can play Earth2140 on some sort of amiga in which I never play on my classic amiga1200 because of all sort of bugs I have with my a1200 hardware :)

Win95 installs well, there is step by step tutorial:

https://docs.google.com/document/d/1hv ... 3sprvZX2GfkRhl4YJBT15FTx0

But it tend to crash and burn, and author of DosBox all the time repeat: DosBox is only for games, windows9x even if runs, will be of no use.

I tried to install some software like photoshop, winamp, but it seems default win95 lucking updates/service packs or what it was, and seeing how offten i crashes when experiment and that DosBox authors always says that it will not work as you wish, i just drop that idea and keep it for games. But it runs, works, with video and sound drivers. win98 works too.

Nice video! :) Great to see the first Fallout-game running there. Will definitely give that a go, as it is one of my all-time favorite games.

Running only in window mode, as in fullscreen it will be 640x480 and my video-capture-device will fuck up, but at least you can see the speed, etc. In fullscreen it faster a bit of course (more "vsync"ed).

ps. turn volume up, music/sounds indeed nice

Fun to see the game work well but your driving was bad. Are you using some kind of game launcher to start games?

I saw Frank (Goos) playing the game here on his X1000. Works well!

@kas1e: Thanks for porting!

Yep, just didn't have time for peg2 tests currently, will check later

:) I just play in it 15 years ago, so forgot all the physics, but after a video done it was better :)

Nope, I just run dos-navigator, and for all games create my own myrun.bat, in which I set DOSBox internal settings (like scaler type, CPU type, etc, etc, it can be done just like it dos commands). But of course, you can just make dosbox.conf for any game you want to run, inside of it put what to do (in autoexec section), made a script which runs DOSBox with that conf file and put an icon on it, so it will be just dbl-click on icon and game runs.

There is also runinDosBox, but I not sure how well it handles everything.

Speed is very good with jit (as you can see), in fullscreen (640x480) it feels very fluid.


@imagodespira

Thanks for all real amiga related work you do with Frank :)

Indy Car Racing 2 (Papyrus Design) runs even on G3 A1 system, but at least here (might be different with larger cache) my brief testing didn't show a tremendous difference between interpretive and compiling core. With the latter, at least hot lapping is quick enough, add other cars or details surpassing GC's F1 Grand Prix (Microprose) "to taste".

I did this with frameskip=1, so I suppose the value the game showed was 100 % higher. Then it was running at 15 fps and less.

Great news. Any chance you can port a frontend game launcher for us wo likes a gui to start the games with? Thanks for porting alot of cool stuff!! Dungeon Keeper is a really good game and it makes Amiga NG more interesting the more games we can play on it.

Possible to port DOSBoxGui?

Nope, Tcl/Tk. All other ones also java, qt and all that. For launchers it always was better to write native code via mui or reaction.
